ㄹ irregular verbs

Verbs and adjectives whose stem ends with a ㄹ 받침 are irregular. Some examples of include 알다, 살다, 열다 and 팔다. These verbs/adjectives don't follow normal conjugation rules required for 받침 containing stems, and instead follow the conjugation rules of non 받침 verbs. Also if followed by ㄴ,ㅂ,ㅅ, then the ㄹ in the stem disappears.

Explanation

Normally verb/adjectives whose stem has a 받침 follows a certain type of rule to conjugate it with a grammar pattern. If you notice in this wiki and many other text books, there is often a (으) in grammar patterns, some examples include A/V + (으)면, A/V + (으)니까. So for example, the pattern A/V + (으)면 has two rules, if it has a 받침 at the end of the stem, add 으면 to the stem, otherwise just add 면 to the stem.

A/V + (으)ㄹ 거예요

For example the verb 먹다 has a 받침, so if combined with, say this grammar pattern: A/V + (으)면, it will use A/V + 으면 since it has a 받침 and it will be conjugated as 먹으면. However verb/adjectives whose stem ends with ㄹ 받침 do not follow these rules like the rest of the consonants.

If these ㄹ verbs are followed by ㄴ,ㅂ,ㅅ, then the ㄹ disappears.

also cases like 로, 면 ㄹ can't be used with (으) cases?

만들다 (to make)	A/V + ㅂ니다 / 습니다	만듭니다	explain (??)
말다 (Don't ~)	V + 지 말다 + 세요	V + 지 마세요	ㄹ collides with ㅅ, so ㄹ disappears. Note in this example 말다 is part of the grammar pattern.
